STOVE-ELITE.

Specification of Letters Patent.

Application filed January 9, 1909.

Patented Feb. 8, 1910. Serial No. 471,376.

To all whom it may concern:

Be it known that I, Evnnnr'r E. THOMP- soN, a citizen of the UnitedStates, and a residentof Kaufman, in the county of Kaufman and State ofTexas, have invented certain new and useful Improvements in Stove-Flues,of which the following is a full and complete specification.

My invention relates to stove-flues of the ventilating type, in whichthe flue passes through a casing with openings inside and outside of thehouse for the passage of foul air, the heat from theflue creating adraft in the casing to draw the foul air out of the house and insure itspassage through and out of the casing.

The invention has for one of its objects the provision of improved meansfor securing the flue in the casing and an improved construction of cowlto cover the delivery end of the flue and hooded to protect theoutlet-openings in the ventilator-casing from rain and snow.

My invention is also adapted to use in utilizing the old construction ofventilatorcasings having an interlining for connection with thesmoke-flue to convey the smoke and gases through the casing that havebecome useless because of the burning out of the lining, by removing thelining, running the flue through the casing, and securing it in positionby my new fastening means.

The details of construction of my invention will be describedhereinafter and illustrated in the accompanying drawings, in whichFigure 1 is a fragmental view of a build ing with my improved flue inposition therein, shown partly in section; Fig. 2, a detail view of thepreferred means of securing the flue and casing in position; Fig. 3, aview showing a modification of the construction of flue with a hoodsecured to the flue instead of to a separate cowl; and Fig. 4, a viewshowing the manner of utilizing ventilator-casings which have theirinner linings burned out.

In the drawings similar reference characters indicate correspondingparts in the several views.

Referring to Figs. 1 and 2, A indicates a building in which my improvedflue is installed, and it consists of a'casing 1, having one endextending slightly above the comb of roof B, while its other end extendsdown below the ceiling C of the upper floor, and is provided withcentrally alined holes 2 in its ends, through which the stove-flue. 3extends and ventilating openings 4c around hole 2- in its lower end andother openings 5 in its side just below its upper surface.

6 indicates an inverted V-shaped plate having a hole 6 for the casing 1and secured thereto by any suitable means to form a weather-proofcovering for the opening in the roof through which the casing isextended.

7 indicates a yoke having a circular collar 8, inclosing the flue 3immediately above casing 1, and held in position therein by means of aset-screw 9 that engages said flue. The arms are extended downwardly ateach side of the casing 1, as shown at 11, and have their lower endssecured to inverted V-shaped supports 12 that straddle plate 6, thepurpose of said yoke being to assist in supporting the weight of saidflue 3 and to hold it in position.

If desired, the vertical portions of the yoke 7 may be made of twopieces and adjustable by means of a bolt 13, secured to one part thatengages a slot 14 in the other part.

15 indicates the cowl that fits over the upper end of flue 3, and isprovided with an offset portion 16 with an annular shoulder 17 thatseats in the top edge of the flue, the lower end of said offset portionbeing formed with a bell 18 that shields the upper end of the casing 1and the outlet-holes 5 in its upper end to prevent rain and snow fromentering said outlets.

In Fig. 3 the flue is shown constructed with a hood or bell 18, securedto or formed integral therewith, so as to dispense with the added lengthof pipe 15 forming the cowl, as shown in Figs. 1 and 2.

The operation of installing my improved flue will be apparent from theabove description and an inspection of the drawings, and a detaileddescription thereof is thought to be unnecessary. It will be apparent,however, that my improved flue is adapted to use with theventilator-casings in common use having an inner lining for the smokeflue after said lining has burned out by use, said lining being firstremoved and the flue then inserted in position in the outer casingcorresponding to casing 1 and 23 in the above description.

In Fig. 4 is shown the manner of utilizing Ventilator casings in whichthe inner linings have burned out, in wlnch the casings are shown withthe lower inner extending flange 31 intact and integral with the casing,while the lining and the upper flange that has burned out has beenremoved and a cap 32 having a central opening 33 is secured over theupper end of the casing to take the place of the burned out flange atthat end. The weather-proof flasher 34 is secured to the outer surfaceof the casing to seat on the surface of the roof, and a yoke (not shown)similar to the yoke 7 described above in connection with Figs. 1, 2, and3 is secured to the flue 36, which is lowered through the opening 33 incap 32 and the opening in the lower end of the casing left by the flange31.

Having described my invention, what I claim as new is- 1. In combinationwith a building having a gable roof, a casing secured in said root andextended above its surface, said casing having centrally alined holes inits ends, a flue mounted in said casing and secured throu h the holestherein, a yoke secured to said flue and having downwardly extendedportions and inverted V-shaped supports on the lower ends of saiddownwardly-extended wardly extended portions,

portions resting on the comb of the roof, substantially as shown anddescribed.

2. In combination with a building having a gable roof, a casing securedin said roof and extended above its surface, the ends of said casinghaving central holes therein in alinement with one another, the lowerend of the casing provided with other holes, the upper end of the casingprovided with holes in its side above the root, a flue mounted in thecasing and in the centrally-alined holes, a yoke secured to the flue andhaving downinverted V- shaped supports on the lower ends of the saiddownwardly-extended portions resting on the comb of the roof, and a cowlconsisting of a tube with an offset to seat on the upper end of the flueand with a bell-shaped hood on its lower end to shield the openings inthe upper end of the casing substantially as shown and described.

In witness whereof, I have hereunto set my hand in presence of twosubscribing witnesses.
